Abstract: PURPOSE:To form a head part in a desired shape by preforming one end of a blank cut to a specified dimension with a preforming punch, then, forming the head parts of headed bar material such as a rivet with a head forming punch. CONSTITUTION:The blank 2 cut to a desired dimension is pushed by the preforming punch 6 into a receiving ring, one end of it is preformed and a diameter expanding part is formed. A ram 8 moving the preforming punch 6 and the head forming punch 7 integrally advances a specified stroke. The forward limit of this preforming punch is detected and stored by a sensor 10. After the blank is preformed, the head forming punch 7 is positioned in front of the blank and the ram advances a specified stroke again. Therefore, the head forming punch forms the diameter expanding part of the blank into a head having a desired shape. The forward limit of this head forming punch is detected and stored by a sensor 10. Two detection values of the sensor are read, compared with reference values corresponding to the punch to decide whether the forward limit of the punch is normal or deflective. Consequently, the head of a specified shape can be formed.

Title: Angle detecting device
Inventor: AIZONO MITSUE
IPC: G02B27/09
Filed: 1993-10-08
Abstract: PURPOSE:To shape a laser beam emitted from a laser light source to an accurate circle so that the angle of the beam can be accurately measured by reflecting the beam with a circular mirror having a diameter smaller than that of the beam. CONSTITUTION:An optical system member 2 composed of a lens, etc., transforms a laser beam 10 emitted from an optical collimator 1 (laser light source) into parallel rays. A half mirror 3 transmits the beam 10 and, at the same time, reflects a beam 11 form a laser circular mirror 4. The mirror 4 has a diameter smaller than that of the beam 10 and is mounted on a plate member 5 treated for preventing reflection. A four-quadrant angle detector 6 detects the angle of the beam 10 based on the light quantity received by each channel in four quadrants by making the beam 11 incident to a sensor light receiving sections. Since the beam 10 is reflected by using the mirror 4 having a smaller diameter, the beam 10 can be shaped to an accurate circle. In addition, the occurrence of stray light can be prevented, because the outer peripheral section of the beam 11 which is not reflected by the mirror 4 is absorbed by the plate member 5 treated for preventing reflection.

Abstract: PURPOSE:To enable a beam finder function to be executed for each channel without providing an exclusive circuit by reducing a DC voltage for controlling gain of an analog multiplier for each channel as compared with normal time for reducing gain when operating the beam finder function. CONSTITUTION:When operating as a normal gain vertical amplifier, a gain control means 32 outputs a positive potential signal for controlling gain to a point b, increases a potential at the point b as compared with a potential at the point a by a specified value + Vab for achieving a corresponding gain. Then, when operating as a beam finder circuit, a means 32 outputs a positive potential signal for beam finder to the point b and increases the potential of the point b as compared with the potential of the point a by a specified value + V'ab, where V'ab<Vab is established and in this state gain is reduced drastically, thus functioning as a beam finder circuit, thereby eliminating the need for providing an exclusive circuit and enabling the beam finder function to be executed for each channel.

Abstract: PURPOSE:To ensure that normal printing can be performed at the time of a printing operation and an ink ribbon can be taken up at high speed at the time of a color changeover of the ink ribbon by providing a condition switching device for setting a torque limiter into an inoperative condition when a printing head is separated from a platen and for setting the torque limiter into an operative condition when the head is pressed against the platen. CONSTITUTION:At the time of printing in a desired color, a heat generating part of a thermal head 11 and an ink ribbon in a color multi-ribbon cassette 4 are facing opposed to each other. With a pulse motor 13 rotated clockwise in this condition, a sun gear 14 in mesh with a pinion gear 12 is rotated counterclockwise, whereby a clockwise moment is given to a planetary gear 16 meshed with a small gear 15 of the sun gear 14. Thus, a force in the direction of an arrow (a) is exerted on the planetary gear 16 due to a frictional resistance, and a gear provided on the lower side of the gear 16 is engaged with a ribbon take-up gear 33. In this condition, the pulse motor 13 is rotated in the same direction at high speed, whereby a desired color part of the ribbon is opposed to the head 11. At this moment, both the ribbon take-up gear 33 and the gear 32 are in mesh with a ribbon lock gear 29, so that a slippage is not generated between both of the gears even in high-speed rotation.
